Why battery warranty cycles matter more than years in SA
SA battery warranties run on years, cycles and throughput, whichever comes first. A claim turns on your BMS data log and how the battery was actually used.
Component Comparisons and Selection
Objective comparisons of battery, inverter and solar module technologies and certification classes for pre-purchase component selection.
Why Your Lead-Acid Battery Dies Early in Load Shedding
Load shedding runs lead-acid batteries on partial-state-of-charge cycling, the duty cycle they handle worst. Here is how cycle life, DoD and C-rate compare.
Why your LiFePO4 battery trips when the kettle goes on
Your battery is not flat. A kettle trips it because the C-rate limit, not state of charge, governs discharge current. How to read the amps and watts.
What solar engineers check in a LiFePO4 home battery
Cell voltage spread, C-rate, depth of discharge, BMS balancing and temperature: what actually decides whether a LiFePO4 home battery in South Africa lasts.
Why an off-grid inverter can never pass the NRS test
An off-grid inverter has no grid-tied input port, so NRS 097-2-1 has nothing to test. Here's how to check what a unit can legally do at the meter.
Why your garage may be killing your LiFePO4 battery
South African garages and roof spaces run far hotter and colder than the datasheet's 25°C. Here's what that does to LiFePO4 cells and what to watch.
Does a three-phase house need a three-phase inverter?
Whether one inverter can back up your whole house depends on your phase configuration and board layout, not your appliance list. Here is how to check.
What a hybrid inverter checks before switching to battery
What a hybrid inverter checks before it switches to battery — and why two quotes with the same panel and battery figures can be very different machines.
Why your lead-acid bank died early, and LiFePO4 may not
Lead-acid banks die early for one reason: depth of discharge and partial charging. Here is how cycle life converts into real years of backup service.
